Rain and solar terms spring ploughing

For agriculture, rain is the key period of spring ploughing management and spring ploughing preparation. After the solar term of rain, the temperature began to rise, the wheat began to turn green from south to north, the water vapor in the soil continued to rise, condensed on the soil surface, frozen at night, melted during the day and began to return to pulp. Due to the increase of rainfall, the air is humid and the weather is warm but not hot, which is very suitable for the growth of all things and has a great influence on the growth of crops in winter. There is a saying that "spring is a treasure after rain".

Before and after rainfall, rape and winter wheat generally turn green and grow, which requires high water content. "Spring rain is as expensive as oil". At this time, proper rainfall is particularly important for the growth of crops. At this time, the rainfall in North China, Northwest China and Huanghuai areas is generally less, which cannot meet the needs of agricultural production. If there is little rain in early spring, spring irrigation in time after rain can achieve the best economic benefits. In the area south of Huaihe River, it is necessary to strengthen farming and weeding, and at the same time, do a good job in field ditches and asphalt to prevent excessive spring rain from causing wet roots.

As the saying goes, "wheat seedlings rape flowers", rape moss should be applied in time to compete for pod weight. South China's double-cropping early rice seedling cultivation has begun, so we should pay attention to "cold tail and warm head", seize the sunny sowing and strive to sow the whole seedling. Do a good job of keeping warm, strengthen disinfection and prevent diseases. The vast number of specialized households should conscientiously sum up the production and operation of the previous year, and then make a good development plan for the whole year. As the temperature rises in Tomb-Sweeping Day, spring will return to the earth, and livestock and poultry production will be in full swing. Farmers' friends should strengthen management and realize the wish of "sowing a millet in spring and harvesting ten thousand kinds in autumn".
